The Secret of Thermal and Spike-Free Laser Diode Testing for Fiber Optics

Chroma_Success_Stories
The Customer

A world-famous manufacturer of fiber optic transceivers, delivering the highest quality of transceivers

The Application

Laser diodes for fiber-optic communication

The Challenge

Laser diodes are extremely sensitive to temperature and spikes: the temperature must stay stable for consistent burn-in, and the driving current should be free of spikes to prevent any latent damage.

The Solution

Chroma 58604 Laser Diode Burn-in and Reliability Test System
